' 'DUMrING- AGON.

Application filed February 20, 1915.

To all whom it may concern Be it known that I, LION L. Wooowann, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Dumping- WVagons, of which the following is a specification.

My invention rclates to an improvement in dumping wagons, more particularly adapted for automobile trucks.

The object is to provide means for the raising and tilting of the wagon-body from a single operating center, as distinguished from mechanism hitherto employed in which one means was used for tilting the body and another for raising and looking it in its raised position.

Thus it is an object of my invention to simplify the mechanism, reduce the number of parts, and facilitate the action of the raising and dumping of the load.

In the accompanying drawings: Figure 1 is a view in perspective; Fig. 2 is a view in side elevation; Fig. 3 is a view showing the body partly raised; and Fig. 4 is a detail.

The numerals 1, 1, represent the sills of the wagon; 2 is the body. The bodyis connected to the sills by two pairs of levers 3 and 4, one of each pair located on each side, and the levers crossing each other. The levers 3 are pivoted at their upper ends to the rear end of the body, the plates 7 being bolted to the body, and having each a stud 6 thereon to form this pivotal connection, the plate 7 being bolted in position when its proper place and adjustment shall have been ascertained. The opposite ends of the levers 3 have sliding connection with the channels 25, the cross-rod 8 connecting thelower ends of the levers 3, 3 having rollers 24 thereon which move in the channels 25. The levers 4, 41, are permanently pivoted at their lower ends to the rear ends of the sills 1, 1, by bolts 5, 5, and their upper ends are connected by the cross-rod 9 which has a roller 24L on each end, which rollers have sliding connection in the channels 23 on the body. The levers 3, 3, are connected at their cen- Specification of Letters Patent.

ters by cross-rod 10, and the levers 4t, 4, each have a quadrant 11 which extends astride this cross-rod 10 and is provided with hooks or notches 12 which with the inner surface of the quadrant adjacent to the notches are 1n position to receive the cross-rod during the lifting and holding action of the levers. Power is applied through a chain 13 which extends from the end 14: of the quadrant part 11 of the lever 4 to the drum 15 on a shaft to which is keyed a large gear 16. This meshes with a similar gear 17 on. the shaft 18, which latter has a large gearwheel 19, the teeth of which mesh withgear 20, on the shaft of which latter the crank 21 is attached, and by the turning of which the body is raised and tilted or lowered into position. In operation by turning the crank, the end 14 of lever 4 is drawn toward the front by the winding of the chain on the drum 15. This raises the front of the body only with the rear end turning in the socket 22, which projects upwardly from the sill. This continues until the cam surface 26 of the quadrant adjacent to the hook 12 comes into contact with the cross rod 10, whereupon it is gradually forced into engagement with the hook 12, which with the further winding causes the entire body to lift from the sills l, 1, as shown in the drawings, the pivots at 5 and 6 being permanent, while the ends 8 and 9 slide in the channels as indicated.

From the foregoing, it will be seen that the parts are few and simplified, the tilting and hoisting, and the return to normal position is effectually accomplished.

I claim:

1. A dumping-wagon comprising sills, body, levers, a cross-rod connecting two of the levers, and the other two levers having a quadrant astride the cross-rod and having means thereon to gradually engage and lift against the rod when the levers shall have moved a certain predetermined distance in one direction.
